A wet footprint by the back door and dog hair on the sofa need different tools. Before buying a Dyson that washes floors, decide whether you also need it to vacuum the rest of your home.
Choose Submarine for mixed cleaning jobs; consider WashG1 alongside a vacuum you already like.
That is our assessment of their designs, not a hands-on verdict. Neither removes the job of dealing with dirty water afterward.
Sofas, rugs and hard floors
Start with Submarine if you need one motor unit for several jobs.
Mostly hard floors
Consider a dedicated washer if wet cleaning is the chore you want to simplify.
You dislike cleaning the cleaner
Read the maintenance section before deciding. Self-cleaning is only part of the routine.

Does either vacuum and mop at the same time?
V15s Submarine uses separate dry-cleaning and wet-cleaning heads. WashG1 picks up debris with rollers rather than vacuum airflow; it does not clean carpets or upholstery. This distinction matters more than the phrase “2-in-1”. Dyson’s WashG1 FAQ explains its limits.
Imagine finishing the kitchen and then cleaning sofa cushions: Submarine can move to a dry tool. With WashG1, you need your separate vacuum. Neither is a robot you can schedule while you are at work.
The practical differences

Submarine: versatility with a head change
Its appeal is keeping dry vacuuming and floor washing in one system. Allow space for the spare heads, and think about where you will rinse the wet attachment. A small hallway cupboard still needs to accommodate the accessories.
Do not buy the wet head to upgrade an ordinary V15: Dyson lists it as compatible only with V15s Detect Submarine. Verify the tools in the seller’s exact bundle. Official bundle and compatibility.

We would consider it when kitchen and hallway washing is the recurring chore, while a separate vacuum already handles rugs and furniture. Carrying a washer upstairs is a different task from pushing it along a floor: consider storage on the level where you will use it.
Dyson lists three water settings and a 140-second self-clean cycle. That can help with the rinse stage; it does not dispose of the dirty water for you. WashG1 functions.

For Submarine, Dyson instructs you to remove and wash the roller, then let it dry. The dry-vacuum filter also needs regular washing. Submarine maintenance.
WashG1’s tanks and debris tray still need emptying and cleaning. Dyson recommends its self-clean cycle after use and manual cleaning every three uses. Follow the manual for your model rather than treating the dock as a fully automatic cleaning station. WashG1 care and maintenance FAQ.
Our buying test: picture yourself doing this after dinner. If a tiny spill is your main problem, setting up and rinsing a powered washer may be more work than the spill itself. If you regularly wash several rooms, the tradeoff can look different.
What Amazon buyers actually reported
In the accessible Amazon.it listing, verified reviews dated 19 July 2024 and 21 July 2024 disagree: one praises washing and fast drying, while another reports streaks and extra wiping. A 6 March 2024 review mentions brush blockages. These are individual experiences from an older listing, not a representative test or current rating. Read the original reviews.
They make one practical question worth asking: does this reduce your whole cleaning routine, including the finishing and rinsing? We could not verify a comparable Amazon review sample for WashG1.
Before you order
Can I use it on parquet?
Check whether your floor’s manufacturer permits wet cleaning and follow both sets of care instructions. A general “hard floors” label cannot settle that for every finish.
Is WashG1 Dyson’s only dedicated washer?
No. Dyson also lists Clean+Wash Hygiene, with an approximately 30-minute warm-air drying function. It still does not replace a vacuum for carpets and sofas. If drying the roller is your priority, compare that model before choosing an older WashG1 offer.
What if I mainly need to pick up hair and crumbs?
